Problems solved by technology

During on-site operation, because there is no specific powder collection device, the dust is usually flying, which not only affects the dust collection rate, but also is harmful to the health of the operator
At the same time, since the impact drill does not have a depth control device, it is difficult to accurately control the powder extraction depth each time. It is usually necessary to stop several times in the middle to measure the depth manually with a ruler, which not only affects the powder extraction efficiency, but also makes it difficult to ensure the powder extraction hole. verticality
Such powder collection results will inevitably have a certain adverse effect on the test results and testers

Embodiment Construction

[0013] In the present invention, a scale is engraved on the sliding rod of the control device, which is accurate to millimeter, and a hoop clip is provided, and the fixing and moving of the hoop clip are realized by adjusting the degree of tightness. When the fixed hollow rod on the outside of the slide bar encounters the hoop clamp, the percussion drill bit will stop moving forward, so the depth of each powder extraction can be controlled by setting the position of the hoop clamp. The dust collector mainly includes a powder collection cylinder and a powder collection bottle. The powder collection cylinder seals the dust drilled by the drill bit in a relatively closed space, and collects the dust into a detachable powder collection bottle through the action of its own weight and the shaking of the device. . In order to closely and vertically stick the powder collection tube to the surface of the structure, a spring is provided at the end of the slide bar near the drilling mach...

Abstract

The invention discloses a durable device for controlling powder taking depth and collecting powder, which consists of a control device and a powder collector, wherein the control device consists of a slider provided with scale and a hoop clamp, and the powder collector consists of a dust collecting barrel and a dismountable dust collecting bottle. The device is directly fixed at the front end of an impact drill, thus accurately controlling the powder taking depth, ensuring powder taking verticality and power taking efficiency and reducing damage of manual work and dust to inspectors.

Description

technical field [0001] The invention relates to a powder-taking depth control and powder-collecting device for engineering structure and material durability, which can precisely control the powder-taking depth and ensure the dust collection rate and the health of operators. Background technique [0002] The durability of engineering structures is one of the most important issues in the field of civil engineering today. In order to evaluate the quality and service performance of structures and predict the service life of engineering structures, it is necessary to perform durability powder testing on materials or structures. At present, the durable powder extraction of engineering structures is mainly done manually by using impact drills. Usually two people are needed to extract powder, one person operates the impact drill, and the other places a plastic bag under the impact drill for dust collection. During on-site operation, because there is no specific powder collection dev...
